What side effects are associated with this type of intervention?

Common treatments for bladder cancer, such as HDAC inhibitors like Belinostat and monoclonal antibody immunotherapies like Durvalumab, have distinct side effect profiles. Belinostat can cause fatigue, nausea, vomiting, and hematologic toxicities such as thrombocytopenia and neutropenia. Durvalumab, an immunotherapy, may lead to immune-related adverse events including colitis, pneumonitis, hepatitis, endocrinopathies, and skin reactions. Both treatments can also cause general side effects like infusion-related reactions and fatigue. Patients should discuss these potential side effects with their healthcare provider to manage and mitigate them effectively.

What prior FDA approvals exist?

The FDA has approved several treatments for bladder cancer that are similar to Belinostat and Durvalumab. Durvalumab, a monoclonal antibody targeting PD-L1, is approved for patients with locally advanced or metastatic urothelial carcinoma who have disease progression during or following platinum-containing chemotherapy. Other similar immunotherapies include Atezolizumab, Pembrolizumab, and Nivolumab, which also target PD-1/PD-L1 pathways. While Belinostat, an HDAC inhibitor, is not specifically approved for bladder cancer, other HDAC inhibitors are being studied for their potential in treating various cancers, including urothelial carcinoma.

What other types of research exist?

Promising alternatives for bladder cancer treatment in 2024 include Enfortumab Vedotin, an antibody-drug conjugate targeting Nectin-4, and Sacituzumab Govitecan, a Trop-2 directed antibody-drug conjugate. Additionally, Pembrolizumab and Atezolizumab, both PD-1/PD-L1 inhibitors, continue to show efficacy in clinical trials. Novel HDAC inhibitors like 4SC-202 are also being investigated for their potential in urothelial carcinoma.

Summary

This trial tests a combination of two drugs, durvalumab and belinostat, for treating advanced urothelial cancer. It targets patients whose cancer has spread or cannot be surgically removed. Durvalumab helps the immune system attack cancer, and belinostat stops proteins that help cancer cells grow.

Who is the study for?

Adults (18+) with advanced urothelial carcinoma that's spread or can't be surgically removed, who've tried at least one therapy or declined/aren't suitable for standard treatments. They must have ARID1A gene alterations, measurable disease, good organ function and blood counts, and a life expectancy of over 12 weeks. Women must not be pregnant and use effective contraception.

What is being tested?

The trial is testing the combination of two drugs: Belinostat (an HDAC inhibitor that may stop cancer cells from growing) and Durvalumab (a monoclonal antibody designed to help the immune system attack cancer). It aims to find the safest dose with acceptable side effects for patients with specific genetic changes in their tumors.

What are the potential side effects?

Potential side effects include reactions related to the immune system attacking normal organs, infusion-related reactions like fever or chills, fatigue, nausea, liver enzyme changes indicating liver damage, low blood cell counts increasing infection risk or bleeding tendency.

Group I: Treatment (durvalumab, belinostat)Experimental Treatment2 Interventions

Phased Doublet Therapy Eligible patients enrolled will be administered durvalumab 1120 mg every 3 weeks C1 through C7 followed by durvalumab 1500 mg every four weeks C8 through C15 (T300+D). Belinostat administration will begin with Cycle 2 for 6 cycles. From cycle 8 on, durvalumab will be administered in 28-day cycles to complete up to a total of 15 cycles of treatment or until treatment discontinuation criteria is met. Belinostat will be administered at the assigned dose level on days one through five of every applicable cycle. Belinostat administration on five consecutive days is preferred. Administration within seven days of Day 1 is allowed as needed to accommodate holidays and infusion schedules. Durvalumab will be infused over 60 minutes (±10 minutes). For Cycles 2-7, belinostat will be infused over 30 minutes (-5 minutes/+15 minutes) and will be administered after durvalumab. Separate infusion bags and filters must be used for each infusion.

Other Research

Bladder cancer treatments often include HDAC inhibitors like belinostat and monoclonal antibody immunotherapies such as durvalumab. HDAC inhibitors work by blocking histone deacetylase enzymes, which play a crucial role in cell growth and death, thereby potentially stopping cancer cell proliferation and inducing cancer cell death. Monoclonal antibody immunotherapies, on the other hand, help the immune system recognize and attack cancer cells by targeting specific proteins on the surface of these cells. For instance, durvalumab targets the PD-L1 protein, preventing it from inhibiting immune responses. These mechanisms are significant for bladder cancer patients as they offer targeted approaches to halt cancer progression and enhance the body's natural ability to fight the disease.
